Billionaire investor Bill Ackman proposed merging U.S. government-sponsored enterprises Fannie Mae (OTCQB:FNMA) and Freddie Mac (OTCQB:FMCC) in a post on X this Sunday. He argued that such a merger would lower mortgage rates and create significant operational and financial synergies.

U.S. President Donald Trump's administration could kick off initial public offerings of Fannie Mae and Freddie Mac later this year, according to a senior administration official, marking a key milestone for the mortgage finance giants that have been under government control for years.
